Abstract
A method of making a synthetic hectorite-type mineral is described, along with its resulting physical and rheological properties. The synthetic hectorite-type mineral is a 2:1 phyllosilicate essentially free of aluminum, and having a trioctahedral structure with Mg2+ and Li+ occupying octahedral sites. As a hydrogel, the synthetic hectorite-type mineral has a swell index of greater than 55 mL, and a yield point of greater than 290 Pa. The method of making uses a MgO/MgCO3 buffer system, with heating for about 2 hours at temperatures of no higher than 300° C. and pressures of no higher than 600 psi.
